It's Complicated

The picture didn't work. Do you see a white spot on the yolk? It sometimes helps to have it in a glass bowl just in case the blastodisc is on the bottom of the yolk.

Can you tell from this pic?

It's hard to tell in the picture. Can you see a darker circle enclosing a white dot within the white circle?
(Looks like a white bullseye with darker/yellow separating the white parts.)
I THINK I see fertility, but I'm not entirely sure.

There is the link showing fertile vs. infertile.
The first picture on the thread is an infertile egg. I am thinking yours is fertile but since you have it in front of you, it'll be easier for you to tell.

There is a white spot.

Hi,

The spot does not have the doughnut ring, it is a solid white dot, but quite large diameter about 5mm.

If this is fertile then hopefully she lays some more and we can hatch them.

I believe I see a darker concentric circle within the big white dot in the photo. If that is the case, then it is fertile!
Will you incubate the next egg and check for fertility by candling after 7 days?
I'm sorry I can't answer your question about how long you can hold them before incubation, but someone else will be along soon to answer those questions.

May I ask, are you in Malaysia?

I used to talk to a bunch of Malays when I played online game starkingdoms, lol.
